I have set an IPN notification URL in paypal website. When I checked the IPN history in my merchant account, it shows the attempt failed. Also I logged the first line of my notification method . But there is no log for the method trigger. What might be the posssible reason for this.
I also tried checking the URL with IPN simulater , but it says "We're sorry, we could not connect to this URL. Please make sure it was entered correctly."
And most annoyingly paypal customer support is responding to my ticket very slowly. Please help.
Even if you get through to paypal technical services, they would tell you the same thing: PayPal can't connect to your listener. I'd recommend checking the listener from outside of your own network environment and making sure it responds with a http 200.
